This security RFID transponder provides an 80-bit encryption algorithm. The 5-byte challenge and 3-byte response algorithm is backward compatible with existing TI products and provides, together with the burst length coding, short encryption telegram times.

The DST80 offers 65 bytes of free programmable user data stored in nine pages, each of them lockable for programming. Each of the two 80-bit encryption keys with can be programmed with a single telegram.

The DST80 comes in two versions, preprogrammed with either PWM or PPM communication formats, eliminating the need for the user to change this field.

For a higher security level, the DSTAES transponder with AES-128 encryption is recommended.
